Pharmacoepidemiological Observational Study of Antimicrobial Use in Outpatients of Ophthalmology Department in North Indian Population.

BACKGROUND: Recognition of drug usage patterns provides the basis for improving safety and plummeting risks associated with their use. Thus, this study was undertaken to explore the drug usage pattern in ophthalmology with an emphasis on antimicrobial use at a tertiary care teaching hospital. MATERIALS AND METHODS: An observational study was conducted in the Department of Ophthalmology, Hakeem Abdul Hameed Centenary Hospital, Jamia Hamdard, New Delhi, India for 9 months. Newly registered patients visiting the Outpatient Department for curative complaints were included. All drugs prescribed were recorded, including dose, route, dosage form, frequency of administration, indications for prescription, and duration of therapy, and the data was audited using the indicators prescribed by the World Health Organization. RESULT: A total of 600 prescriptions were analyzed. The number of drugs prescribed was 1097 with an average drug per prescription being 1.8. The most common disorders diagnosed were infective conjunctivitis (21.5%) followed by stye (5.5%). Drugs were prescribed in different dosage forms with eye drops (72.6%) being the most common. Drugs were predominantly prescribed by brand name (100%). Antimicrobials (44.7%) were the most commonly prescribed drugs followed by lubricants (17.5%). Moxifloxacin (53.5%) was the most commonly prescribed antimicrobial agent. Of the antimicrobials prescribed, 89.6% were prescribed topically. Average total cost per prescription was 113 INR. CONCLUSION: The study concludes with an overall impression of rational prescription in terms of prescribing in consensus with the recommended treatment protocol of ocular diseases. Nevertheless, health-care professionals should be encouraged to prescribe by generic name. Creating awareness regarding selection of drugs from essential drug list to reduce the drug cost is the need of the hour. Last but not least, updating knowledge regarding appropriate antimicrobial use and the development of discreet strategies for their use should be implemented to steer clear of antimicrobial resistance.
